I have this Samsung BN44-00438C REV:1.1 power supply that has shorted Mosfet QP801 a couple of times.
Initially just replaced mosfet however it has since gone again so suspect the fan ic however i cannot identify the number properly it could be a fan 7530 or a fan 7930 (ICP801)? Does anyone know which one it is please as I cannot rely on the schematic giving the right details as some of the component values are different from the one on the psu board! I will also be checking the surrounding components for any issues
Please reply if you know for certain which one it is! Thanks
